UNITED STATES PATENT EEICE THEODOR BSSLER, OF NEUSS, GERMANY.

PULP-ENGINE SPECIFICATION forming part of Letters Patent No. 716,172,dated December 16, 1902.

Application filed November 8. 1901. Serial No. 81,526. (No model.)

T0 all whom it may concern:

Be it known that I, THEoDoR BSSLER, a citizen of Germany, and a residentof Neuss,

Rheuish Prussia, Germany, have invented` certain newandusefullmprovements in Pulp-p` Engines, of which the following is aspecification.

This invention relates Ato a pulp engine which will effect a thoroughtrituration ofthe mass. The accompanying drawing is a plan,partly insection, of my improved pulp-engine.

The letter t represents a horizontal casing having contracted ends t',which are coupled" to a horizontal tube 1^, so as to form a contin-`uous horizontal. passage. At the center the casing t is enlarged to forma squared chamber which is wider than tube r and accommodates thehorizontally-hung triturating-roller w. The shaft w3 of this rollerextending across tube fr turns in Vbearings w' and` is driven frompulley wz.

ber of casing t is provided with two tapering or coniform ends whichmerge at their apex into the inwardly-turned contracted necks t. Thepulp moved forward by roller w in a horizontal direction will begradually compressed within the contracted necks and will be forcedrapidly through the comparatively narrow The squared cham# tube fr tobecome thoroughly mixed and uniformly triturated. 4 The casing 25,'aswell as the return-tube o, are arranged in a horizontal plane, so thatthe pulp need not be lifted :during trituration and deposits will notacl contracted necks, and with a triturating-roller within the chamber,substantially as speci fied.

Signed by me at Dsseldorf, Germany, this 29th day of October, 1901.
